Anthropogenic ocean noise can have adverse effects on migratory species, such as disturbance to communication between individuals or disruption of navigation. Through its various instruments and working groups, Convention on the Conservation of Migratory Species of Wild Animals (CMS) has recommended Parties to undertake research of the impact of underwater noise, and to limit or mitigate man-made noise to address SDG 14 Target 14.1.

Resolutions have been adopted at the last two Conference of the Parties (2008 and 2011), which address the severe impact of marine noise, and has allowed the progression of scientific research and its implementation into policy. These resolutions have given rise to the development of guidelines on Environmental Impact Assessments for Marine Noise-generating Activities, which have been submitted for review at the upcoming COP 12, as well as consolidations of resolutions and decisions.

The Joint Noise Working Group (JNWG) of CMS, ACCOBAMS and ASCOBANS also serves as an advisory group to ensure the continuous progress towards mitigating the negative impact of underwater noise on cetaceans and other marine biota. The JNWG also works to reduce the effects of underwater noise generated because of offshore construction of renewable energy sources, such as offshore windfarms, and developed extensive mitigation measures in 2014 for windfarm construction. The need for the implementation of these guidelines will be reaffirmed at COP 12, putting emphasis on ongoing coordinated research on the impacts on migratory species.
